I'm fine with pm-utils writing the preamble and postamble. But I want to 
create the log file from HAL (e.g. solution 3. in the mail I just sent), 
not rely on some magic file location that would have to be part of the 
pm-utils ABI.

Be careful not to pack too much info into the preamble; only include 
"dynamic" information e.g. kernel state, kernel version, lsmod output, 
/proc/meminfo, /proc/sys/kernel/tainted, (maybe) what X driver is being 
used and so on. This is because it will always run and thus needs to be 
very fast.

The desktop policy manager can, upon handling the error on reboots go 
bananas and include all the "static" stuff about the system such as 
lshal output and whatnot. That too (including a decision to send it to 
fd.o bugzilla, module pm-utils) would probably be good to standardize - 
let's cross that bridge when we (that is, you and Richard!) get there.
